Question

1. two technicians are discussing the evaporators function in an automotive air - conditioning system. all of these are true about the evaporator except: it removes humidity from the air. refrigerant flows from the bottom to the top. refrigerant enters the evaporator as a liquid. the refrigerant changes from a vapor to a liquid as it receives heat from the cabin air.

Explanation:

In an automotive - air - conditioning system evaporator, refrigerant enters as a liquid, absorbs heat from the cabin air and changes from a liquid to a vapor, removing humidity in the process. Refrigerant typically flows from bottom to top. The statement about changing from vapor to liquid as it receives heat is incorrect as it should change from liquid to vapor upon heat absorption.

Answer:

The refrigerant changes from a vapor to a liquid as it receives heat from the cabin air.
